[Effective Stress Principle & Terzaghi 1D Consolidation Concept 3] In a saturated clay layer of thickness $H$ with two-way drainage, the time factor $T_v$ for $50\%$ consolidation is $0.197$. If the coefficient of consolidation is $c_v = 4 \times 10^{-4}\text{ cm}^2\text{/s}$ and $H = 4\text{ m}$, how much time is required for $50\%$ consolidation?
